~anthropic/claude-sonnet-latest → A (3:1)

Side A fixes a real logic bug (zero-ratio votes silently defaulted to 1:1 instead of being rejected/dropped) and adds sensible bounds with focused, well-tested changes across parser, handler, and reducer. Side B is a large syntax-reordering refactor (moving explanation blocks before votes/items) that touches many files and fixtures but is mostly mechanical churn with no functional bugfix, and even changes the DSL in a way that could be seen as a regression in ergonomics (losing adjacent-body syntax).
